Some provisional results from analysis of skyline data from DIVINE and ASSIST projects.
Diurnal variation in CO2 flux, N2O flux, PPFD and air temperature, averaged over all experiments.
Diurnal variation in CO2 flux, N2O flux, PPFD and air temperature, averaged separately for each experiment
Diurnal variation in CO2 flux, N2O flux, PPFD and air temperature, averaged separately for each day. Separating by each day gives equal weight to days with little variation, so shows relative variation rather than absolute variation.
Diurnal variation in CO2 flux, N2O flux, PPFD and air temperature, averaged separately for each experiment and for each day but pooling all chambers within an experiment and day. Separating by each experiment and day gives equal weight to both experiment and days with little variation, so shows relative variation rather than absolute variation.

Response of N2O flux to air temperature. Colours show data for each experiment, with a best-fit regression line for the pooled data set.
Response of N2O flux to air temperature with logarithmic y-axis. Colours show data for each experiment, with a best-fit regression line for the pooled data set.
Response of N2O flux to soil temperature. Colours show data for each experiment, with a best-fit regression line for the pooled data set.

Response of N2O flux to volumetric water content. N2O fluxes are normalised wrt the maximum flux for each experiment. Panels show data for each experiment, with a beta function estimated for the pooled data set.
